i have a 2007 cobalt LS i have it fully built and added a custom turbo kit making 350whp and 380tq
i am constantly breaking axels, im also slammed on Stance GR+ coilovers and i have yet to take a locking ring out to get the stanced look that im soon going for.
i was told the TTR STOP mounts would help prevent this but TTR has replied and told me these will not fit my car.
anyone have ideas to what can help prevent axel braking?

 

How about better axles from the drive shaft shop we carry. You simpley have to must torque on a small stock axle shaft.

 

No no no, that is horrible information. Think physics! All mounts do is stiffen up one vibration point. Energy cannot be destroyed it can only be redirected. Therefore, if the torque isn't moving your engine (motor mounts) and if it isn't moving your transmission (tranny mounts) then it's going straight to your axles.

This is how you get better acceleration in a FWD car, but it also puts a ton of stress on your axles.

So, long story short, TurboTechRacing is correct. What you want to do is get some high horsepower axles. It's the only way you're going to prevent breakage. Also take into consideration where the axles attach to the transmission (spline count). If that is weak, you can have the strongest axles in the world, the amount of torque you're putting down will tear them right out of the transmission under hard launches.

Welcome to the world of drag racing. One mod gets you horsepower but means you need more mods, lol.

 

Powell F23 rotated mounts, aligns the axles so they aren't so angled and you'll stop breaking them.

 

^^ this And zzp stg 1 f23 axles

 

Read my post. That doesn't make any sense. Energy has to go somewhere. Stiffening the rotation of the transmission only means more torque is traveling the full journey to the axles and wheels.

I broke axles ONLY AFTER putting mounts on.

 

they're napa axles..

 

it depends on the reason you're breaking axles if you're breaking them due to axle bind then rotated mounts can help

 

U Prevent axles from breaking by not spelling axles like u did (axels) when u go to get new ones

 

Not for the f23...the f35 ones are

 

Haha no offensive but I don't think you understand the concept. Having no intermiate shaft on the F23 the unequal and improperly aligned axles make a HUGE difference when put in correct alignment with the torque axis of the transmission output shaft. Rotated mounts don't actually "stiffen" the rotation of the transmission much at all, that is the point. Even regular mounts that do "stiffen" the movement of the transmission don't actually transfer more or less torque to the axles/wheels, they just increase the rate/shock of the initial torque output. You can't really understand this by applying simple physics, you need to understand the entire system as a whole.

 

you have proof on that? I bought napa axles for my f23 and they were a good amount thicker then the stock ones

 

how much were they? that's pretty awesome

 

Or just stop shifting like an animal. That'll do wonders for your car.

 

same price as zzp's minus shipping.. just make sure you get the new ones... not the refurbished ones

can someone provide me with the website to the rotated mounts please?
the one i broke the most is the drivers side and thats a napa being replaced 4 times, my drives side axle has broken last weekend and it was stock with 130,000km on it
thanks for the help

 

You have to email Gloria, the sales lady at gloria@powellraceshop.com she will take good care of you and answer any questions you have. With the power your making I would suggest the stage 2 mounts, just make sure you specify F23 mounts. Your a 5-speed right?

edit: saw your VB garage, you are. I highly suggest these and definitely think they will sure your axle breaking problem. BTW awesome car you got right there!

 

You're probably right about the axles, but the guys at napa were dicks about it so I just bought them from Zzp...oh well

 

you could always not slam your car and not have your cv's at crazy angles...

 

Gtfo!!!! It looks cool dog, it's a lifestyle.

 

he can either not slam his car, and put the power down.

he can slam his car and burn through axles.

he can slam his car, get with powell and get mounts to raise the drive train and put the power down.

 

I just do it all like a boss

 

^^doing it right.

My car makes no power, and I has powell mounts and stg 1s, be cuz racecar/slammed

 

noob question but can someone explain or link me to the difference between rotated mounts and poly inserts? thx

 

Rotated mounts bring the front of the tranny down, and the rear up to help align the tranny with the hubs to keep the axles strait and free of bind. Poly mount don't really do anything except vibe your teeth loose.
